# Which issue does this PR close?
None
# Rationale for this change
The current example for python UDF is useful but doesn't demonstrate to a
new user how they might implement a UDF using converting rows to python objects
vs using features built in to pyarrow. This example shows a real use case where
someone could perform such operations. Also it prints out timing results
showing how using a pyarrow approach can give you a 10x speed improvement over
converting to python objects.
